Blinded T-bends used in pneumatic transport lines are characterized for having a long life. In this work was studied the effect of gas velocity, solids flow rate and bend orientation on the wear and flow patterns inside this kind of bend. Gas velocities up to 30 m/s, in dilute phase conditions were tested in a 2 inch I.D T-bend made of glass. The orientations tried were horizontal to horizontal, horizontal to vertical upwards and vertical upwards to horizontal. The different flow patterns were photographed and the deposition of solids was characterized in a gas velocity-solids flow diagram. Depending on the operating conditions and bend orientation, a wedge of solids accumulated in the dead end zone, resisting the primary impact of the erodent. For the erosion tests, the glass surface was painted, and the wear patterns were determined for different orientations and regimes. 5 refs., 12 figs., 1 tab.
